oh Kara, just been reading along, you poor thing, you must be SO frustrated! i know how frustrated i get when Caleb doesnt nap, even more so when i walk him in the stroller for an hour and he STILL doesnt sleep, but to be pregnant as well, gosh i really feel for you! is the room at your Mums place darkened? I know Caleb will not sleep in another cot/pack in play/whatever no matter how i make it like his room, unless its really really dark, otherwise he gets distracted by the "new" room but with it dark enough he cant see it and cant focus on it... have you tried that>?
